NJNM2625A
PWM TYPE 3-PHASE DC BRUSHLESS MOTOR CONTOROL IC
♦GENERAL DESCRIPTION
The NJM2625A is a 3-phase DC brush-less motor
control IC with PWM control.
It incorporates hall amplifiers, PWM control circuits,
totem-pole pre drivers for external power MOS
transistors, current limit and frequency generator
circuit.
The NJM2625A easily implements speed control
and rotation direction control for DC motor application.

• A rotation direction change must be made after motor stopped completely.
• When PWM duty is extremely small, two or more switching elements cannot be driven entirely.
In such case, switching elements will generate excess heat and it may cause destruction of the
switching devices. Therefore, extensive heat evaluation is necessary for switching device selection
particularly in consideration of the area of safety operation (ASO).
